Embodiment 1

[0061] It is suitable for pre-embedded pipelines in shallow pavement, which includes a pavement pre-embedded groove 1, and a base layer 2 is arranged in the pavement pre-embedded groove 1, and its difference lies in that a pipeline reinforcement component is arranged on the base layer 2 3. Support channels 4 are distributed in the pipeline reinforcement component 3 . In this way, multiple groups of pipelines distributed in the same direction can be laid and protected. Considering the bearing capacity of the support channel 4 for longitudinal stress, the support channel 4 is provided with auxiliary support rods 5, and the upper and lower ends of the auxiliary support rods 5 are aligned with the support channel. 4 The inner walls are in contact.

[0062] A partition assembly 6 is distributed on the periphery of the support channel 4, which can effectively partition the downward water seepage from the surface of the road surface. Thus, an airtight protective space is formed betw...

Embodiment 2

[0074] The pre-embedded pipeline suitable for the shallow layer of the pavement includes a pavement pre-embedded groove 1, and a base layer 2 is arranged in the pavement pre-embedded groove 1. The difference between it and the prior art is that: There is a pipeline reinforcement component 3, and support channels 4 are distributed in the pipeline reinforcement component 3. In this way, multiple groups of pipelines distributed in the same direction can be laid and protected. Considering the bearing capacity of the support channel 4 for longitudinal stress, the support channel 4 is provided with auxiliary support rods 5, and the upper and lower ends of the auxiliary support rods 5 are aligned with the support channel. 4 The inner walls are in contact.

Embodiment 3

[0087] It is suitable for pre-embedded pipelines in shallow pavement, which includes a pavement pre-embedded groove 1, and a base layer 2 is arranged in the pavement pre-embedded groove 1. Supporting channels 4 are distributed in the reinforcement assembly 3 . Meanwhile, an auxiliary support rod 5 is arranged in the support channel 4 , and the upper and lower ends of the auxiliary support rod 5 are in contact with the inner wall of the support channel 4 . In order to effectively block the downward water seepage of the pavement surface, a partition assembly 6 is distributed around the support channel 4 . Thus, an airtight protective space is formed between the partition assembly 6 and the periphery of the support channel 4 . At the same time, a filling layer 7 is arranged in the protection space. Moreover, in the present invention, a backfill layer 8 is distributed in the pavement embedded groove 1, and a barrier layer 9 is laid on the backfill layer 8.

Abstract

The invention relates to a pre-embedded pipeline suitable for shallow pavement, which includes a pre-embedded pavement groove, and a base layer is arranged in the pre-embedded pavement groove. A supporting channel is distributed, and auxiliary supporting rods are arranged in the supporting channel. At the same time, a partition assembly is distributed on the periphery of the support channel, a filling layer is arranged between the partition assembly and the periphery of the support channel, a backfill layer is distributed in the pre-buried pavement groove, and a barrier layer is distributed on the backfill layer. Therefore, while satisfying the laying of multi-legged pipelines, it can effectively bear the stress from the outside and protect the internal pipelines from impact. Also, prevent groundwater from infiltrating and corroding. Furthermore, it can withstand the downward longitudinal stress from the ground, preventing subsequent pipelines from being longitudinally squeezed.

Description

technical field [0001] The invention relates to a pre-buried pipeline, in particular to a pre-buried pipeline suitable for shallow pavement. Background technique [0002] As far as the existing municipal engineering (municipal engineering) is concerned, it refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (townships), and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. At the same time, the construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, and various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity ( The part outside the red line), telecommunications, heat, gas, etc., as...
